On the inside pages of the issue, she’s floral and flirty as she poses in Alexander McQueen, Oscar de la Renta, the Row, Versace, Vera Wang and more for famed fashion photographer Terry Richardson.

The September 2012 issue of ‘Harper’s Bazaar’ is the largest issue ever with 375 ad pages and in her Stefani’s cover story, she opens up about her style, staying fit, balancing her career and motherhood, and more.

The September 2012 issue of ‘Harper’s Bazaar’ hits shelves on August 21st.

Here’s what Gwen Stefani had to say:

On her style: “I’ve always been a girl who loves to dress up. I already put my makeup on twice today: I put it on to take my kid to school, and then I went home, washed my face, and put it on again to have lunch with you. I like to make my husband like me more and he likes it when I’m wearing makeup.”

On staying fit: “I hate talking about my body [all the time]; it’s ridiculous. There is no secret: You just have to eat healthy, work out, and torture yourself! I like to wear clothes too much, so I try to keep focused.”

On motherhood: “It’s superfun being a mom, but it’s hard too. Finding that balance between work and family is the hardest thing I’ve ever done—by far.”

On fame and gossip: “That someone would say something untrue or bad about me doesn’t bother me. It’s like water off a duck’s back. None of that stuff matters. There’s something in me, being this passive person, that those kinds of things don’t upset me. I know they can say anything; they can just make something up. But what are you going to do? It’s not part of my reality, so it’s okay.”

On her iconic red lip: “I remember sitting in my ghetto, beat-up Honda Prelude and putting on that lipstick in the rearview mirror and being like, ‘Uh-huh, I like that. That’s the shit right there.’ I never stopped after that.”
